Rails - Jan 2006 - recongizing the current controller in views

alright i am doing a simple self blog in ruby. Now iw ant to be able to 
determine which controller action i am in inside _form.rhtml.

So if i am in new or the creation control than i want to insert the text box 
for topics else i want to display the topic base on id. (i could do those 
already, i just need help finding the right if statement..

something like (if currentpage == "blogs/new") ....<input type =
text...

I want to be able to do this inside the view.

Kevin,

In addition, I''m in my first rails app and already grouping my
controllers
into modules e.g:

app/controllers/crm
app/controllers/crm/customer_controller.rb
app/controllers/crm/mailing_controller.rb

app/controllers/mgmt
app/controllers/mgmt/product_controller.rb
app/controllers/mgmt/vendor_controller.rb

Is there a way to point out the module (or controller group if you will)
I''m
in?

Thanx!

GrtzG

I think controller.controller_path might give you
''module/controller''

On further investigation it seems that controller.controller_path is not 
callable from a view.  The method exists in the  ActiveController::Base 
class, but for some reason I can''t get it to work.  My guess is that 
there is something in the way rails handles method inheritance that is 
preventing it from working in a subclass.  If you copy the code from the 
base file to your application controller, it may work.  At the very 
least, you should be able to determine how to return the module name 
from the code.

It may also be possible to do this by writing a custom routing rule that 
accounts for the module.

Kevin,

Thanx. Over my head for now, but maybe I''ll write a helper that gets me
the
name of the parent dir the controller is in.

Regards,

Gerard.

I think @controller.class.controller_path should work.  I''m using that 
in a layout at the moment.

if you look closely at the activecontroller::base code you will see that 
controller_path is defined as a singleton method (I think).  This means 
you need to use the controller.class.controller_path to access it.

The other controller functions have normal public methods defined for 
them that call an underlying class method.  Apparently someone forgot to 
write one for controller_path.

since they used the ''class << self'' idiom to define
several methods in
the core, it is not at all obvious from the RDocs that this method 
should be treated like a class method, hence the confusion.

Good tip, Alex.
